A - 3b = 4
a = b -2
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b = 4 + 2
-2b = 6
b = 6/-2
b = -3
a = b - 2
a = -3 -2
a = -5
to check: a = -5 ; b = -3 ⇒ (-5,-3)
a - 3b = 4
-5 - 3(-3) = 4
-5 + 9 = 4
4 = 4
20-14=6 6-3=3 3/20 is the answer for the fraction of ounces left
It is 45 because the triangle should be 180 degree and if K is 45 then J should be 45, too. We all know that the right triangle is 90 degree, so we add angle J and G, it is 135. Lastly, you subtract 180- 135=45.
Answer: -19x
Step-by-step explanation: In this problem, we're asked to simplify the expression.
The two parts of this expression, -8x and 11x are called terms. The numbers in front of the variables are called coefficients.
Because the variables, x and x are identical, the terms get a special name and they're called like terms.
To subtract like terms, we simply subtract their coefficients and add the variable on to the difference of the two numbers.
Since -8 (-11) is -19, -8x - 11x simplifies to -19x.
